WO3 is High-temperature superconductor-like structured and crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent W6+ sites. In the first W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 4–10°. There are a spread of W–O bond distances ranging from 1.85–2.04 Å. In the second W6+ site, W6+ is bonded to six O2- atoms to form corner-sharing WO6 octahedra. The corner-sharing octahedra tilt angles range from 4–10°. There are a spread of W–O bond distances ranging from 1.85–2.04 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the second O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the third O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the fourth O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the fifth O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the sixth O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the seventh O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the eighth O2- site, O2- is bonded in a linear geometry to two equivalent W6+ atoms. In the ninth O2- site, O2- is bonded in a linear geometry to two W6+ atoms. There is one shorter (1.87 Å) and one longer (2.00 Å) O–W bond length. In the tenth O2- site, O2- is bonded in a linear geometry to two W6+ atoms. There is one shorter (1.88 Å) and one longer (2.00 Å) O–W bond length. In the eleventh O2- site, O2- is bonded in a linear geometry to two W6+ atoms. In the twelfth O2- site, O2- is bonded in a linear geometry to two W6+ atoms.
